Assemble the cardboard boxes. Make sure each crease is crisp and sturdy.

Arrange the boxes in five rows of five boxes each, and make sure each one is facing the same direction.

Decorate the lids with washi tape (or your preferred decorations).

Top with lablels numbered 1 to 25. The labels can be arranged randomly, in order counting up from 1 to 25 or counting down from 25 to 1.

Once you have the boxes how you'd like them, start gluing each box together to create five rows. With the glue gun, draw two lines of the glue on the side of the box, then quickly adhere the box to the one next to it. Be careful to get the edges to match. Allow the glue to cool & dry before moving onto the next box.

Once you have all five rows glued together, glue the rows together. Draw two lines of hot glue all the way across the side of a row, then quickly adhere it to the adjacent row. Line each row up carefully so the edges match. Allow the glue to cool/dry before moving onto the next row.

When your grid is complete, attach a piece of cardboard to the back with hot glue. This helps to make the calendar sturdy. (Remember, it is going to fit 25 mini bottles of booze!) Decorate the top of the box with ribbon, if desired.

Fill each box with the crinkle paper for padding, then a mini-bottle of liqueur. Make sure the bottle is well-padded, especially if it is glass.

Close up the boxes and you're ready to display your booze advent calendar! Cheers!
